FRED HASKELL FRIEDMAN, OF ROCHESTER, NEW YORK.

SCREEN-FRAME.

Specification of Letters Patent.

Patented Nov. 26, 1918.

Application filed February 12, 1918. Serial No. 216,802.

. To all whom it may concern Be it known that I, FRED HASKELL FRED- MAN,a citizen of the United States, residing at Rochester, in the county ofMonroe and State'of New York, have invented certain new and usefulImprovements in Screen Frames, of which the following is aspecification.

This invention relates to improvements in frames for screens and itsobject is to provide rails and corner braces which are adapted to clampand hold a metal screen between them.

Another object of this invention is to so construct this frame that itcan be easily fitted to any door or window.

With these and other objects in view, the invention presents a novelconstruction comprising a combination and arrangement of parts whichwill be fully illustrated in the drawings, described in theSpecification and pointed out in the claims at the end thereof.

In the accompanying drawings,

Figure 1 is a perspective view of a corner of a frame embodying theinvention.

Fig. 2 is a perspective view of the corner brace and the rails attachedthereto, the corner brace and the rails being shown divided along themiddle thereof ready to receive and clamp a metal screen between them.

Fig. 3 is a vertical sectional view of one section of the corner braceand the rail attached thereto, the section being taken on the line 3 -3of Fig. 2.

Fig. 4: is a similar sectional view of the companion section of thecorner brace and its rail, the section being taken on the line r a ofFig. 2.

Fig. 5 is a perspective view of a modified form of the corner brace.

Fig. 6 is a perspective view of an angle brace for connecting horizontalrails to the vertical rails.

Fig. 7 is a perspective view of a corner of a frame showing a modifiedform of the corner brace for clamping together the rails and screen ofthe frame.

Fig. 8 isa perspective view of the two sections of the corner braceshown in Fig. 7.

Fig. 9 is a sectional view of one of the sections of the corner braceand the rail fastened therein, the section being taken on the line 9"-9"of Fig. 8.

In the several figures of the drawing, like reference numerals indicatelike parts.

The frame comprising this invention is bullt up of a series of parallelrails l and 2 which are connected at their ends by the corner braces 3to form the corners of the frame. These corner braces are made up in twosections which are preferably stamped and bent up out of sheet metal. Asshown in Figs. 1 and 2, the sections 4: and 5 forming one of the cornerbraces 3 comprise an angular channel 6 with a cover plate 7 bent overthe central portion thereof. This cover plate is integral with each ofthe sections and divides the angular channel 6 into two pockets, each ofwhich i adapted to receive the end of one of the rails 1 or :2.

When the rails are inserted into these pockets, the sides of the coverplate 6 which are adjacent to the pockets, act as a stop for the railsand serve to properly locate them therein. The rails 1 and 2 arefastened into the pockets of each of the sections 1 and 5 by suitablewood screws, and the sections 4: and 5 with the rails 1 and 2 attachedthereto are then clamped together by means of the machine screw 8 and 9.These machine screws pass through holes provided in the outside of thesection 5 of the corner brace 3 and project through corresponding holesin the cover plate 7 of the same section and then engage with thethreaded holes 10 and 11 provided in the cover plate 7 of the section 4of the corner brace.

In this manner, ections 4: and 5 of the corner brace 3 together with therails 1 and 2 are rigidly clamped side by side to form a complete frame.The metal screen 14 is tightly clamped in place between the rails 1 and2 and the cover plate 7 of the sections 4 and 5 of the angle braces.

T provide space sufiicient to prevent the rails 1 and 2 and the anglebraces from spreading when the metal screen is inserted between them,the rails 2 and the cover plate 7 of the sections 5 of the angle bracesare provided with a ridge 13 which encircles the outer edge of the innerside of the rails 2. This in turn provides the small channel between therails 1 and 2 and the section of the corner brace when the frame is puttogether, so that the metal screen can be placed between the rails 1 and2 before they are clamped together and clamped in place between themafterward without spreading the rails and corner braces as shown in Fig.1.

Because of the clamping of the metal screen between the rails along thewhole perimeter thereof, the metal screen does not need to be tackeddown or otherwise fastened thereto. If desired, however, the screen maybe fastened to the rails in any suitable manner after it has beenclamped in place between them.

From the foregoing it will be seen that a screen frame of this kind canbe made up of stock rails and corner braces and to fit a screen to anysize of opening, window or door only stock rails need be secured and cutto the desired length and fastened ixr gether by means of the stockcorner braces which will clamp the rails together with a metal screen ofcorresponding length between them.

To fasten and connect cross rails to the vertical rails, angle bracesare used. These angle braces are made up of two sections 15 and 16 whichare Milt up of sheet metal similar to the corner brace sections a and 5except that the cover plates 7 are omitted therefrom. This is necessarybecause the rails 1 and 2 pass clear through the sections of the anglebraces and the rails forming the cross rail abut against the sides ofthe vertical rails. Suitable screws areprovided to clamp the sections ofeach of the angle braces together and hold the vertical as well as thehorizontal rails in place therein.

In Fig. 5 is shown a modified form of a corner brace, which ispreferably formed as a casting. This corner brace instead of be ingprovided with a cover plate re form a stop for the rails when insertedinto the pockets on each end of the corner brace is "formed with a stopwhich is integral with the casting and for this purpose the middleportion of the angle brace is left solid except for a pocket 17 in oneof the sections and a lug 18 in the other section. The lug 18 of onesection is adapted to project into the pocket 17 in the other sectionand when the metal screen is is placed between them, the lug 18 willforce a portion of the screen into the pocket 17 and rigidly lock it inplace therein.

The addition of the lug 18 and pocket 17 also serves to prevent thesections of the corner braces from endwise movement and properly locatesthem side by side with relation to each other.

"The web 20 on each of the sections of the corner braces is provided forthe purpose of reinforcing the inner corner thereof.

The modified form of angle brace 21 shown in Figs. 7 8 and 9 has thecover plate 7 omitted therefrom, so that each end of the sections 22 and23 comprising the angle brace is bent up in the form of a plain L shapedchannel. The rails 1 and 2 are adapted to project into each end of thesechannels so that their ends abut against each other in the middlethereof and form a miter joint between them.

Both of the rails 1 and 2 shown in Figs. 7, 8 and 9 have the ridge 13provided around their perimeter on the inner side so that the screen 14when placed between these rails will be held in the exact middle betweenthem.

In the corner brace shown in Figs. 7, 8 and 9, the sections are'heldtogether by means of wood'screws which pass through one side of each ,ofthe sections and screw into both of the rails and thus hold each of thesections in place on the rails in addition to clamping the rails side byside to hold the metal screen between them.

It will be understood that instead of clamping the screen between therails, a glass panel or any other panel may .be in serted instead.
